transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Depositor with respect thereto; (iv) any review by the Underwriters of the Depositor, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Depositor; and (v) the Underwriters’ obligations to the Depositor in respect of the offering, purchase and sale of the Registered Certificates are set forth in this Agreement in their entirety.

For the purposes of this Agreement, “Free Writing Prospectus” shall mean a “free writing prospectus” as defined pursuant to Rule 405 under the 1933 Act. If, subsequent to the date of this Agreement, the Depositor and the Underwriters have determined that the Time of Sale Information included an untrue statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and the applicable Underwriters have terminated their old purchase contracts and entered into new purchase contracts with investors in the Registered Certificates, then “Time of Sale Information” will refer to the information available to investors at the time of entry into such new purchase contracts, including any information that corrects such material misstatements or omissions (“Corrective Information”).

(xxvi) The Depositor has executed and delivered a written representation (the “17g-5 Representation”) to each Rating Agency that it will take the actions specified in paragraphs (a)(3)(iii)(A) through (E) of Rule 17g-5 of the 1934 Act, and the Depositor

(A) If an Underwriter becomes aware that, with respect to any investor in a Registered Certificate, as of the Time of Sale, any Issuer Information contained in any Underwriter Free Writing Prospectus and delivered to such investor was not correctly reflected in such Underwriter Free Writing Prospectus such that it caused the Underwriter Free Writing Prospectus to contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in the light of the circumstances under which they were made, not misleading (such Free Writing Prospectus, together with a Defective Issuer Free Writing Prospectus, a “Defective Free Writing Prospectus”), such Underwriter shall notify the Depositor and each other Underwriter thereof within one (1) business day after discovery.

- 21 -

(C) With respect to this clause (xiii), each Underwriter agrees that if the Depositor requests that an Underwriter prepare a Corrected Free Writing Prospectus with respect to a Defective Free Writing Prospectus that another Underwriter prepared, such other Underwriter will prepare the Corrected Free Writing Prospectus and will deliver the Corrected Free Writing Prospectus to the Depositor and each Underwriter so that each Underwriter may contact its respective investors.

(D) To the extent any Defective Free Writing Prospectus was defective as a result of incorrect Issuer Information being delivered to an Underwriter, the Depositor shall provide such corrected Issuer Information upon request from such Underwriter. The Depositor shall also notify the other Underwriters of such incorrect Issuer Information, to the extent it is provided notice hereunder.

(xiv) Such Underwriter covenants with the Depositor that after the final Prospectus is available, such Underwriter shall not distribute any written information concerning the Registered Certificates that contains any Issuer Information to a prospective investor in a Registered Certificate unless such information is preceded or accompanied by the final Prospectus.

(b) Each Underwriter, severally but not jointly, agrees to indemnify and hold harmless the Depositor, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Depositor within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions (when read in conjunction with the Time of Sale Information) made in the Registration Statement (or any amendment thereto), any Issuer Free Writing Prospectus, any Time of Sale Information or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Depositor by such Underwriter expressly for use in the Registration Statement (or any amendment thereto), any Issuer Free Writing Prospectus, any Time of Sale Information or the Prospectus (or any amendment or supplement thereto) (collectively, “Underwriter Information”); provided that no such material misstatement or omission arises from an error or omission in information relating to the underlying data regarding the Mortgage Loans or the related Mortgagors or Mortgaged Properties provided by the Depositor or any Mortgage Loan Seller to such Underwriter. In addition, each Underwriter, severally but not jointly, shall indemnify and hold harmless the Depositor, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Depositor within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all losses, liabilities, claims, damages and expenses, as incurred, arising out of any (i) untrue statements or alleged untrue statements of a material fact, or omissions or alleged omissions to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in the Underwriter Information, and (ii) untrue statements or alleged untrue statements of a material fact, or omissions or alleged omissions to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in any Underwriter Free Writing Prospectus or that arise out of or are based upon the omission or alleged omission to state in such Underwriter Free Writing Prospectus a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that no Underwriter shall be obligated to so indemnify and hold harmless (A) to the extent the Depositor is entitled to indemnification or contribution therefor under the indemnity of any Mortgage Loan Seller set forth in the related Mortgage Loan Purchase Agreement or set forth in any Service Provider Indemnification Agreement, or (B) with respect to information that is also contained in the Time of Sale Information, or (C) to the extent such losses, liabilities, claims, damages or expenses are caused by a misstatement or omission resulting from an error or omission in the Issuer Information supplied by the Depositor or any Mortgage Loan Seller to an Underwriter which was not corrected by Corrective Information subsequently supplied by the Depositor or any Mortgage Loan Seller to such Underwriter at any time prior to the Time of Sale. Notwithstanding the foregoing, the indemnity in clause (ii) of the immediately preceding sentence will apply only if such misstatement or omission was not also a misstatement or omission in the Prospectus. Furthermore, no Underwriter shall be obligated to indemnify or hold harmless the Depositor or any other person or entity otherwise entitled to such indemnification or to be held harmless under

- 31 -

this subsection (b) for any liability that is based upon or arises from the information set forth in the eighth and ninth paragraphs, the first sentence of the tenth paragraph, and the eleventh paragraph under the caption “Method of Distribution (Underwriter)” in the Prospectus (or any amendment or supplement thereto) to the extent that both (1) such information is based upon and is in conformity with the information set forth in the Prospectus (or such amendment or supplement thereto) that is not Underwriter Information and (2) such non-Underwriter Information either contains an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or fails to comply with Regulation AB.

It is hereby acknowledged that the statements set forth in (i) the penultimate paragraph on the cover of the Prospectus, (ii) the third sentence of the seventh paragraph under the caption “Important Notice Regarding the Offered Certificates” and (iii) the first and third sentences of the fourth paragraph, the eighth and ninth paragraphs, the first sentence of the tenth paragraph, and the eleventh paragraph under the caption “Method of Distribution (Underwriter)” in the Prospectus constitute the only written information furnished to the Depositor by the Underwriters expressly for use in the Registration Statement (or any amendment thereto) or in any Issuer Free Writing Prospectus, any Time of Sale Information, or the Prospectus (or any amendment or supplement thereto).

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability under Section 8(a) or Section 8(b) hereof (unless the indemnifying party is materially prejudiced by such failure) or any liability that it may have otherwise than on account of the indemnity provided by this Section 8. Upon request of the indemnified party, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding as incurred. An indemnifying party may participate at its own expense in the defense of any such action and, to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from the indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have agreed in writing to the retention of such counsel, or (ii) the indemnifying party shall not have assumed the defense of such action, with counsel satisfactory to the indemnified party, within a reasonable period following the indemnifying party’s receiving notice of such action, or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. In no event shall the indemnifying party or parties be liable for fees and expenses of more than one counsel (or, in the event the Depositor or ▇▇▇▇▇ Fargo Bank is the indemnifying party, one counsel for each Underwriter) (in addition to any local counsel) separate from its or their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in

- 32 -

the same jurisdiction arising out of the same general allegations or circumstances. Unless it shall assume the defense of any proceeding, an indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld) but, if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party shall indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel or any other expenses for which the indemnifying party is obligated under this subsection, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. If an indemnifying party assumes the defense of any proceeding, it shall be entitled to settle such proceeding with the consent of the indemnified party or, if such settlement provides for an unconditional release of the indemnified party in connection with all matters relating to the proceeding that have been asserted against the indemnified party in such proceeding by the other parties to such settlement, which release does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, without the consent of the indemnified party.

(d) The indemnity provided by this Section 8 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by the Depositor, ▇▇▇▇▇ Fargo Bank, the Underwriters, any of their respective directors or officers, or any person controlling the Depositor, ▇▇▇▇▇ Fargo Bank or the Underwriters, and (iii) acceptance of and payment for any of the Registered Certificates.

The indemnity provided by this Section 8 will be in addition to any liability that any Underwriter, the Depositor or ▇▇▇▇▇ Fargo Bank may otherwise have.

Contribution.

(a) In order to provide for just and equitable contribution in circumstances in which the indemnity provided by Section 8 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, or if such indemnification provided for in Section 8 hereof is unavailable or insufficient in respect of any losses, liabilities, claims, damages or expenses referred to therein, the Depositor and ▇▇▇▇▇ Fargo Bank, jointly and severally, and the Underwriters, severally, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by the indemnity provided by Section 8 hereof incurred by the Depositor and the Underwriters, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Depositor and ▇▇▇▇▇ Fargo Bank on the one hand and each Underwriter on the other hand from the offering of the Registered Certificates or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Depositor and ▇▇▇▇▇ Fargo Bank on the one hand and of each Underwriter on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations (taking into account the parties’ relative knowledge and

- 33 -

access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission or failure to comply, and any other equitable considerations appropriate under the circumstances). The relative benefits received by the Depositor and ▇▇▇▇▇ Fargo Bank on the one hand and the Underwriters on the other hand shall be deemed to be in the same respective portions as the net proceeds (before deducting expenses) received by the Depositor from the sale of the Registered Certificates and the total underwriting discounts and commissions and other fees received by the Underwriters in connection therewith bear to the aggregate offering price of the Registered Certificates. The relative fault of the Depositor and ▇▇▇▇▇ Fargo Bank on the one hand and of each Underwriter on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Depositor and ▇▇▇▇▇ Fargo Bank or by the Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation; and no Underwriter shall be obligated to contribute more than its share of underwriting discounts and commissions and other fees pertaining to the Registered Certificates less any damages otherwise paid by such Underwriter with respect to any such loss, liability, claim, damage or expense. It is hereby acknowledged that the respective Underwriters’ obligations under this Section 9 shall be several and not joint. For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and such Underwriter’s officers and directors, shall have the same rights to contribution as such Underwriter, and each director of the Depositor, each officer of the Depositor who signed the Registration Statement, and each person, if any, who controls the Depositor within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Depositor.

(b) The parties hereto agree that it would not be just and equitable if contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take account of the considerations referred to in subsection (a) above. The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses referred to in Section 8 hereof or this Section 9 shall be deemed to include any legal fees and disbursements or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such claim except where the indemnified party is required to bear such expenses, which expenses the indemnifying party shall pay as and when incurred, at the request of the indemnified party, to the extent that it is reasonable to believe that the indemnifying party will be ultimately obligated to pay such expenses. In the event that any expenses so paid by the indemnifying party are subsequently determined to not be required to be borne by the indemnifying party hereunder, the party which received such payment shall promptly refund the amount so paid to the party which made such payment. The remedies provided for in Section 8 hereof and this Section 9 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

(c) The contribution agreements contained in this Section 9 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any

- 34 -

investigation made by the Depositor, ▇▇▇▇▇ Fargo Bank, the Underwriters, any of their respective directors or officers, or any person controlling the Depositor, ▇▇▇▇▇ Fargo Bank or the Underwriters, and (iii) acceptance of and payment for any of the Registered Certificates.

10.

Default by an Underwriter.

If any one or more Underwriters shall fail to purchase and pay for any of the Registered Certificates agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally (in the respective proportions which the portion of the Registered Certificates set forth below their names in Schedule I hereto bears to the aggregate amount of Registered Certificates set forth below the names of all the remaining Underwriters) to purchase the Registered Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase; provided that no Underwriter shall be obligated under this Section 10 to purchase Certificates of a Class that it is not otherwise obligated to purchase under this Agreement, and provided, however, that in the event that the amount of Registered Certificates that the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Registered Certificates set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Registered Certificates, and if such non-defaulting Underwriters do not purchase all of the Registered Certificates, this Agreement will terminate without liability to any non-defaulting Underwriter or the Depositor, except as provided in Section 11 or Section 12 hereof. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date for the Registered Certificates shall be postponed for such period, not exceeding ten (10) business days, as you shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Depositor and any non-defaulting Underwriter for damages occasioned by its default hereunder.

11.

Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Depositor and ▇▇▇▇▇ Fargo Bank submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, or by or on behalf of the Depositor and ▇▇▇▇▇ Fargo Bank, or by or on behalf of any of the controlling persons and officers and directors referred to in Sections 8 and 9 hereof, and shall survive delivery of the Registered Certificates to the Underwriters.

12.

Termination of Agreement; Survival.

(a) The Underwriters may terminate their obligations under this Agreement, by notice to the Depositor, at any time at or prior to the Closing Date (i) if there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Depositor,

- 35 -

▇▇▇▇▇ Fargo Bank or any other Mortgage Loan Seller whether or not arising in the ordinary course of business, (ii) if there has occurred any outbreak of hostilities or escalation thereof or other calamity or crisis the effect of which is such as to make it, in the reasonable judgment of any Underwriter, impracticable or inadvisable to market the Registered Certificates or to enforce contracts for the sale of the Registered Certificates, (iii) if trading in any securities of the Depositor or of ▇▇▇▇▇ Fargo Bank has been suspended or limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or on the NASDAQ National Market or the over the counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, (iv) if a banking moratorium has been declared by either federal or New York authorities, or (v) if a material disruption in securities settlement, payments or clearance services in the United States or other relevant jurisdiction shall have occurred and be continuing on the Closing Date, or the effect of which is such as to make it, in the reasonable judgment of such Underwriter, impractical to market the Registered Certificates or to enforce contracts for the sale of the Registered Certificates.

(b) If this Agreement is terminated pursuant to this Section 12, such termination shall be without liability of any party to any other party, except as provided in Section 11 or Section 12(c) hereof.

(c) The provisions of Section 5(e) hereof regarding the payment of costs and expenses and the provisions of Sections 8 and 9 hereof shall survive the termination of this Agreement, whether such termination is pursuant to this Section 12 or otherwise.

13.
